ok, then please try the following
- apply the attach patch
- reboot your machine and load the (non-working) alsa driver first.
  check whether it really doesn't work
- get the register dump from /proc/asound/card0/ymfpci
- get the pci registers via "lspci -vvxxx" (only for the ymfpci
  device)
- unload alsa module, load oss, check the performance
- unload oss, and reload the alsa again.
  check the performance.
- if it works at this stage, get the reg dump.
  also, get pci registers.
- compare the two dumps.


TIA.

Takashi
